Have I got my sums wrong?

An early flight to Zurich today meant getting up at 4am so throughout the day I have been fighting off fatigue. When I arrived at the hotel I was able to get straight to the pool for a pretty solid hours swim. Then this evening out for a 45 minute run with the intention of inserting a 5 mins period at zone4. However I really struggled to get my heart rate above 162. By my calculations I should be able to get to around 170. If however, my max heart rate is 162 then I need to be bringing down the average heart rate I am working at during the aerobic sessions. I will re-test tomorrow and see what I can achieve then take a view on it. Legs are a little tired after the half marathon on Sunday which I am not surprised about.
